Reborn in the Apocalypse: The Vast Changes of Time and Space

This story is entirely fictional. Please don't take it seriously! Don't do anything foolish, and don't let anyone deceive you. The apocalypse is complete nonsense! Please, everyone, don't be silly! The universe shed a cell, and the stars changed a strand of hair. The Milky Way took a new breath, and Earth turned over. Naturally, the life forms on Earth had to change as well, and so came the end of the human world. Superpower version: The apocalypse arrived. Shikong thought that, aside from natural and man-made disasters, nothing else would be left. But that wasn't the case. Shikong gained spatial powers, but couldn't celebrate. People dragged them off to a research institute, and then they thought they were a goner. But that wasn't the case either. They were reborn?! They still couldn't celebrate, because the apocalypse was waiting just ahead. Why hadn't they gotten a golden finger? Well, that's not quite true either. Uh! I did give them one, actually. It's just a little slow going. It does have world-defying potential, but you'll have to discover that for yourself! Rebirth version: Shikong had always regretted being so willful and keeping Mom and Uncle Ye from getting married. They regretted believing their so-called father, Bai Fei, which led to their family's deaths. They regretted falling out with Li Jiang, who died saving them... Oh, right, Li Jiang was reborn too! Uh! You two... Since you have regrets from the past, make things right and make up for them. Otherwise, what was the point of being reborn? Science fiction version: There are meteorites and radiation, seas turning into mulberry fields and mountains into deep valleys, but time, temperature, climate, and the like are gone... The apocalypse means everything is gone, all of it. Gone! There are spaceships fleeing into space and arks diving beneath the sea. A new ecosystem brings new energy sources, which in turn give rise to the origins of new species. There's not just love and hate, passion and grudges, but also absurd, melodramatic gossip. The siblings, though, aren't really siblings. There are not only men and women, young and old, but also hermaphrodites and people without sex, so there's both romance and danmei. There are not only bizarre monsters, but also superpowered zombies, though no cultivation. The story imagines dinosaurs and the Maya, and even dreams up merfolk and beastmen, but there can be no omnipotent gods. This is only a soft science-fiction conjecture, or perhaps a fantasy. Serious researchers, please stand down. I'm just telling a story, and I know my skills are average. If you really can't get used to it, click the red X in the upper-right corner.
